What is cryptography ?
Data security explain in hindi
hello dosto
kaise ho aap.. aaj ka topic start krne se phle mera requset hai ki agr apne mera YouTube Channel subscribe nhi kiya hai toh kar le... because meri kosis hai ki me aap ko easy language me Ethical Hacking ke bare me knowledge de saku...
Toh chaliye.... aaj hum jaanege ki cryptography kya hota hai to sabse phale baat karte hai cryptography ki.
what is Cryptography
cryptography ka agar hum definition ki baat kare to cryptography ka meaning hota hai “apne data ko secure karna” means the art of protecting data.
So dosto agar hum simple language me bole to iska matlab hai ki mera ek data hai usko mai change karke ek ase code me change kar duga jo ki kisi ko smz me na aaye mai jisko wo data send kar rha hu wo data usko hi smz me aayga kyonki main usko yaa to koi hint duga ki isko ase samjna hai.
but ye sab kaise hoga to sabse phale hum apne data ya jo bhi humare paas information hai usko unreadable (secrets code) me change kar dege jinko hum chiper text bhi kahte hai.
or wo person jiske paas is secret key hogi wo hi isse decrypt karke read karega decrypt hui data ko hum plain text kahte hai.

types of cryptography
cryptography me two process hoti hai
1.encryptions
2.decryption
Encryption : me plain text ko cipher text me convert kiya jata hai.
mane uper aapko bataya hai ki plain and cipher text ky hota hai.
decryption :me isse ulat hota hai isme simply cipher text ko plain text me convert kiya jata hai data ko readable banane ke liye.
